How to remove basic license?

I installed the basic license with marvel. Later I installed watcher and tried to put a watcher in ES but got the following error

[401] {"error":{"root_cause":[{"type":"security_exception","reason":"current license is non-compliant for [watcher]","license.expired.feature":"watcher"}],"type":"security_exception","reason":"current license is non-compliant for [watcher]","license.expired.feature":"watcher"},"status":401}

I searched the internet to find that watcher does not work with basic license. Is there a way to downgrade the basic license to trial license?

After searching for long the only solution was to reinstall license, watcher and marvel.


the basic license is only valid for marvel, but it is not for watcher. So either you go for 30 days with the trial license and then upgrade to basic to have marvel working or you have two different clusters for this, one with the trial license for testing and one marvel cluster with the basic license.

There is no need for a reinstallation of the plugins though.
